White Out Hardenbergia is the white-flowered form of Happy Wanderer - the same vigorous, adaptable WA native climber and groundcover but with clean white pea flowers rather than the more familiar purple. The white form is less commonly grown, which makes it more interesting in mixed plantings where standard Happy Wanderer is already present. It flowers in late winter and spring, producing masses of small white pea flowers in dense clusters. Can be trained as a climber on a fence or trellis, used as a scrambling groundcover on a bank, or allowed to mound freely. Full sun to part shade. Well-drained soil. Phosphorus-free fertiliser. Drought tolerant once established.
